STONE-BREAKER.

Specification of Letters Patent.

Patentedfiept. 25, 1917..

Application filed March 2, 1915. 1 Serial No. 11,615.

To al whom it may concern:

Be it known that I, ANTONIO T. CAnozzA, a citizen of the United States, residing in Baltimore county, State of Maryland, have invented a new and useful Improvement in Stone-Breakers, of which the following is a be easily located with reference to the stone to be broken.

A further object of my improvement is the providing of a swinging guide for the upper end of the hammer whereby the same may have a directed path of action in its upward movement toward a predetermined point, and

A further object of my improvement is the providing of an improved hammer for breaking stone traveling in a guided path free to swing.

With the foregoing and other objects in view my invention consists of the novel construction, combination and arrangement of parts as herein specifically described and illustrated in the drawings wherein is shown the preferred embodiment of my invention, but it is understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

r Fig. 7 is an enlarged view of the foot of the In the drawings of the herein described embodiment of my invention Figure 1 shows a view in elevation of my improved stone breaker; Fig. 2 shows a View in elevation taken at right angles to that shown in Fig. 1; Fig. 3 shows a plan view; Fig. 4 is an enlarged View of the hammer, its guide broken off and the support for the guide; Fig. 5 shows a plan view of the support for the guide which is shown in elevation in Fig. 4; Fig. 6 shows a sectional view of the track of the crane taken at A B of Fig. 1 looking toward the mast or upright. and

strut supporting the track.

Similar numerals refer to similar parts throughout the several views.

1 is a platform or vehicle, preferably mounted on tracks 2, which may be conveniently laid adjacent to the stone operated upon. 3 is the mast or upright. l is the buggy track upon which is operated buggy 5. 6 is the strut supporting buggy track 4:. 8 and 9 are guy members and are side supports also.

Mast or upright 3 is pivotally mounted to platform 1 at 10, at its foot and pivotally mounted to guy members and side supports 8 and 9 at 11. 12 is a gear secured to mast or upright 3 and operated by pinion 13, which pinion is pivotally mounted to platform 1 and operated by hand wheel 14:. 15 is the hammer, having guide lugs 16 at its head and operating face 17 at its lower end. The hammer is substantially tapered from its upper end with a small hardened face at its lower end. 18 are the guides upon which hammer 15 operates by means of guide lugs 16 and which guides operate through support 19 secured to buggy 5. 20 are stops on guides 18 secured thereto. 21 are adjustable stops, operated on and secured to the upper ends of guides 18 and support said guides.

Hammer 15 is operated by cable 22 operating over pulley 23. Buggy 5 is operated on track 4 by cables 24 and 25, cable 25 being operated over pulley 26. 27 and 28 are stops on track 4: limiting the movement of buggy 5. Cables 22, 24 and 25 are operated by engine 29 as desired. The foot of strut 6 is secured into shoe 30 by pin 31. 32 is the stone to be broken.

The operation of my invention is as follows:

Tracks 2 are laid in proximity to the stone to be broken and platform or vehicle 1 placed in such a position, and within range, so that the stone may be reached. Bugg track 1 being secured to mast or upright 3, is swung into proper position by hand wheel 1 1 and buggy 5 operated on buggy track 4 out and in, these various movements are such as to break stone wherever desired within range of the machine. Guide rod 18 is adjusted as to height by means of adjusting stops 21 so that there is some space on guides 18 between stops 20 and guide lugs 16 when the hammer is at the limit of its stroke.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A stone breaker consisting of a support, a carriage adjustable thereon, guide rods suspended from said carriage at their upper ends and a hammer vertically movable on said guides and having 'a'lower free end adapted to project below said guide rods, said guide rods being supported only at their upper ends and free throughout their depending lengths.

2. A breaker consisting of a support, a guide operatively controlled by said sup bqpies -of this patent may be obtained for port and free to swing throughout its entire 10 depending length and a hammer embracing said support and mountedon said guide so as to operate below the same.
